2005 Annual Report 4d.Progress report. This report serves to document research conducted as a result of a specific cooperative agreement between ARS and the Oregon State University, Department of Horticulture. Additional details of research can be found in the report for the parent project 5358-21000-033-00D, "Management of Temperate Adapted Fruit, Nut, and Specialty Crop Genetic Resources and Associated Information". In the Fall/winter 2005-2006, 10 tissue samples will be collected from about 10 different cultivars of hardy kiwifruit that are established at the USDA ARS National Clonal Germplasm Repository in Corvallis, Oregon, and the North Willamette Experiment Station of Oregon State University, in Aurora, Oregon. These samples will be collected every two weeks from October 15 through March 15. Samples will consist of a 5 node, 1 year old fruiting cane section. Samples will be forced under warm conditions. The days to bud break will be counted and contrasted to determine the chilling requirement for each cultivar. In the spring 2006, date of bud-break, first and last flower, and fruit harvest date (female vines) will be collected. A correlation analysis between these data and the chilling requirement will be performed. This will be he first year of a two year study. Reports will be written after the two years data are collected.
